I get this if I fret hard, I refer to it as 'clank' though.
I always thought that it was a technique thing, and I can relate since mine isn't that good either.
I have to work harder to avoid clank as I move up the fretboard, the first 3-5 frets I don't get it at all. So I would expect a higher action to increase clank, the opposite of what some said.
My strings are ultra-light - this could make for slappier strings because the tension is low, making it easier to hit other frets when smacked down hard, especially as you move away from the nut.
My action is low - which as far as I can tell helps.
And unlike what some have suggested, it has nothing to do with plucking, I can get plenty of clank purely from the left hand.
Try a hammer on (but without first fretting a nearby fret) on the E string around the 9th fret and you should get a nice clear clank, and the B string is even clankier, I am pretty sure that is what the OP is talking about, or at least that is what happens to me.
Hoping to glean some ideas from this thread too.
